Magnuson's absence in spring practice further complicates several position battles along Michigan's offensive line heading into next season as the Wolverines will have to replace both left tackle Taylor Lewan and right tackle Michael Schofield.

Sophomore Ben Braden is expected to compete for the starting left tackle position, while both Kyle Kalis and Kyle Bosch were considered locks to compete at both guard spots. Graham Glasgow and Patrick Kugler are expected to battle at center, and Magnuson was expected to be in play at right tackle.

Moving forward, Hoke says current redshirt freshman David Dawson (6-foot-4, 297) could see a heavy look at right tackle this spring, along with classmate Logan Tuley-Tillman (6-foot-7, 300).

"I think we've got enough guys still (to get a look on who will be in position to start this fall)," Hoke said. "David Dawson has a chance to be a good player. Ben Braden, I think we all felt he got better as the year went on and so he's going to get multiple reps.

"I thought Blake Bars played better (at guard/center), he was on the look team (last year). Then you've got Bosch and Kalis and Glasgow, Jack Miller, Kugler, Logan ... we'll obviously start with a five, but all that's going to be competitive."
